RSM, the 6th largest global network of advisory and audit services, conducted the financial vendor due diligence for the Roger Delattre Group, a family-owned group based in Boulogne-sur-Mer, specializing in the structure and envelope of buildings, during the equity investment by Nord Capital Partenaires, a leading investor in equity financing for companies in the Hauts-de-France region.

Through this transaction, the Corporate Finance division strengthens its advisory positioning on primary LBOs (Leveraged Buyouts) for family-owned mid-market companies during their capital opening.

Founded in 1959 in Boulogne-sur-Mer, Groupe Roger Delattre is a family-owned business specializing in the structure and envelope of buildings. Positioned at the intersection of structural, insulation, waterproofing, and durability issues, the Group is a leading player in the energy transition sector. In 2022, the Group generated revenues between €85 million and €90 million, with continued growth expected in 2023 in a future-oriented construction segment.

The Group has grown through dynamic internal growth and acquisitions to expand its offerings, addressing building structure, insulation, waterproofing, and durability issues. It is now organized around 10 subsidiaries, including Roger Delattre, PMN, R&D, STM, SMBI, STM, Eurescal, and the recently integrated Façade et Toitures company. The Group employs over 400 people, primarily based in the Hauts-de-France region and Île-de-France.

The Roger Delattre Group is entering a new phase by allowing its executives to acquire shares and welcoming Nord Capital Investissement, managed by Nord Capital Partenaires, a subsidiary of Crédit Agricole Nord de France and Turenne Groupe, following a competitive process led by Capstone Finance. The shared goal is to continue developing expertise, enhance the offering, and accelerate the growth strategy, including a targeted acquisition plan for external growth over the coming years.

The Group’s historic shareholder, Reinold Delattre, accompanied by his partner Bertrand Crépin, stated:

"We are delighted to have a partner like Nord Capital, which shares our values and, with their sector and regional expertise, will be able to support us in our development dynamics."

Anne-Sophie Parguey, Investment Director at Nord Capital Partenaires, added: 

"We are proud to support the Roger Delattre Group, its shareholders, and its management in this new phase. The Group has all the strengths needed to implement its ambitious development plan for the coming years and tackle the sector’s transformation challenges, especially in energy transition."
